Viper's Lair checks out the Thermaltake Smart Fan... Ahh, not a big fan of
these things, they seem more like gimmicks to me. CHeck otu what they thought!

As you probably know, faster fans usually, always result in more noise.
Now, to be honest, in about 99% of all cases, your heatsink fan will likely
drown out the noise of the case fans (more on how we can fix that later), but
cutting down the decibals with quieter case fans is a good start. In comes Thermaltake's
Smart Fan. Whereas before, it only came with the heatsink, now you can buy it
off the shelf as a standalone fan.
